The hydronic module options are compatible only with closed heat exchange fluid loops.
The use of hydronic modules on open loop system is prohibited.
Typical diagram of the hydronic circuit with the hydronic module
legend:
components of the unit and hydronic module
1 Screen filter (mesh opening 1.2mm = 20 mesh), Victaulic
2 Expansion tank (option 293)
3 Relief valve
4 Available pressure water pump
5 Water drain valve
6 Flow switch for the evaporator
7 Evaporator
8 Evaporator heater for freeze protection (option 41A & 41B)
9 Heater for freeze protection of hydronic module (option 41 B)
10 Air purge (evaporator)
11 Water purge (evaporator)
12 Pressure sensor
13 Water temperature probe
Installation components
14 Air purge
15 Flexible connection
16 Shut-off valve
17 Charge valve
18 Pressure gauge
19 Water flow control valve
20 Bypass valve for freeze protection (if shut-down valves -item 16 - are closed)
---- Hydronic module (option)
notes :
The unit must be protected against freeze.
The evaporator is protected against freeze with electric heaters (option 41A factory installed)
The hydronic module of the unit and the evaporator are protected against freeze with electrical heaters (option 41B factory installed)
The pressure sensors are assembled on connections without schraeder. Depressurized and empty the network before intervention
